我想要做的是使用图形、表格和替代图形标题，放置在左侧或右侧，具体取决于当前页面是奇数还是偶数。
感谢用户的大力帮助，回答了我的两个问题floatrow：更改奇数页和偶数页的标题位置和floatrow：更改奇数页和偶数页的标题位置（续），该floatrow包用于自动定位图形和表格对象的标题。
我也想使用一个新对象，它将包含一张图片，但标题名称不应是“数字”我们可以把它叫做“另类人物”。因此我创建了一个信息框（见下面的代码），我尝试以与图形和表格相同的方式使用它，但它似乎不起作用。
任何想法都将受到赞赏。

答案1
软件包floatrow文档说不要将它与软件包一起使用float，但您可以在 MWE 中使用它。以下是摘要的第一句话：“此软件包是作为 float 软件包的扩展而创建的。floatrow 软件包借用了 float 和 rotfloat 软件包的核心代码，因此您不能加载这些软件包。”
因此，要在 的上下文中完成这些事情floatrow，请参阅第 4.1 节“如何替换\newfloat为\DeclareNewFloatType”。结果，我删除了该float包，并用 替换了您\newfloat的\DeclareNewFloatType{infobox}{placement=tbp,fileext=ext}。
最后，您设置了altfigure环境以利用侧边字幕，但后来却无法使用它……您仍然直接调用环境infobox。因此，文档调用从infobox变为 altfigure。
